When using a realtime system for data acquisition or control, there is often a need to transfer files between the real time device and a PC. There are many ways to do this, but newer Linux-based NI CompactRIOs come with WebDAV and SSL support enabled by default. This makes WebDAV an easy option to use right out of the box. The first time I used it, I noticed a couple pitfalls that are worth documenting. This will be a brief post to point out those details. For this post, I used an NI cRIO-9068.

There's plenty to love about the field-programmable gate array, or FPGA. It is essentially a customizable silicon chip that you can reprogram as many times as you want or need to in order to achieve specialized high-speed processing. In many cases, you may have a low-volume product for which an application-specific integrated circuit (ASIC) would be prohibitively expensive. An FPGA is simply a generic grid of logical units on the chip that can be interconnected programmatically, allowing you...
